SPI not working on 5.10 and 5.11, bisected to 766c6b63aa04 ("spi: fix client driver breakages when using GPIO descriptors")

[Christophe Leroy]

Hello,

My board has powerpc 885 microcontroler. Temperature sensor is an LM74.

Kernel has CONFIG_SPI_FSL_SPI and CONFIG_SPI_FSL_CPM and CONFIG_SENSORS_LM70.

Since kernel 5.10, 'sensors' reports temperature 0°C on my board:

	root at vgoip:~# sensors

	lm74-spi-0-5
	Adapter: SPI adapter
	temp1:         +0.0 C

	lm74-spi-0-1
	Adapter: SPI adapter
	temp1:         +0.0 C

With commit 766c6b63aa04 ("spi: fix client driver breakages when using GPIO descriptors") reverted, 
it is back to work:

	root at vgoip:~# sensors

	lm74-spi-0-5
	Adapter: SPI adapter
	temp1:        +38.9 C

	lm74-spi-0-1
	Adapter: SPI adapter
	temp1:        +37.2 C


What shall I do ?

Thanks
Christophe
